About BabyBillion
BabyBillion is India's No.1 kids content brand, reaching billions of views every month across platforms. We are now scaling beyond content into digital products, and our mobile app is the core growth engine for the next phase.
The BabyBillion app is where millions of kids and parents will come to watch, learn, and engage every day. We are building experiences that need to feel fast, reliable, and delightful at massive scale.
Our app is live on playstore and has already crossed 10L downloads.
About the Role
We are a small, fast-moving team building products that actually get used - not just launched and forgotten. We care about clean design, smooth interactions, and solid engineering under the hood.
We are looking for an Android Developer to help build the BabyBillion app from the ground up. Someone who knows Compose like a friend, writes Kotlin like it is second nature, and is curious about what Kotlin Multiplatform (KMP) can really do.
If you get excited about shipping things, learning fast, and owning your work end-to-end, you will fit right in.
What You Will Do
Build the BabyBillion App
- Own features from idea to release - design, code, test, ship.
- Write clean, scalable Kotlin code using Jetpack Compose, Coroutines, and Modern Android Architecture (MVVM/MVI/Clean).
- Build core app experiences - content discovery, watch experience, onboarding, engagement loops, and more.
- Optimize for performance, battery life, and buttery-smooth UI on a wide range of Android devices, including low-end phones in tier 2/3 India.
- Integrate APIs, manage state elegantly, and make the UX shine.
Kotlin Multiplatform (KMP)
- Share business logic between Android and iOS with Kotlin Multiplatform.
- Collaborate on common modules (networking, models, utils).
- Help shape how KMP fits into our mobile architecture going forward.
Work Hand-in-Hand with Design
- Bring Figma designs to life - pixel-perfect, responsive, accessible.
- Give feedback on UX flow and animations.
- Build reusable Compose components that make the app scalable and beautiful.
Keep Things Solid
- Use Git properly - branches, PRs, code reviews.
- Write tests where it matters (unit, UI, or snapshot).
- Help improve CI/CD and release automation.
- Keep a close eye on app performance, analytics, and crash reports.
Collaborate and Contribute
- Work closely with backend, product, and design teams to ship real features.
- Share best practices and contribute to tech discussions.
- Be proactive about improving the dev experience for everyone.
What We Are Looking For
- Experience: 3–6 years of solid Android development experience.
- Core Stack: Deep knowledge of Kotlin, Android SDK, and Jetpack Compose.
- Async and DI: Good understanding of Kotlin Coroutines, Flow, and Dependency Injection.
- Jetpack: Familiarity with Room, Retrofit, and other Jetpack components.
- KMP: Beginner to intermediate hands-on with Kotlin Multiplatform.
- Version Control: Comfortable with Git/GitHub or GitLab and code reviews.
- Ownership: Can take a feature from spec to production with minimal hand-holding.
Bonus Points If You Have
- Experience building consumer apps, content apps, or video-heavy apps.
- Worked on video playback, streaming, or media-heavy features (ExoPlayer, etc.).
- Experience optimizing apps for low-end Android devices and slow networks.
- Experience collaborating directly with designers using Figma.
- Familiarity with Firebase, Crashlytics, or App Distribution tools.
- Played around with CI/CD pipelines (GitHub Actions, Bitrise, or Jenkins).
You Will Fit Right In If You
- Love solving problems and learning new things fast.
- Care about the details that make an app feel great.
- Take ownership - from commit to production.
- Communicate well and collaborate without ego.
- Want to help shape the future of a growing product team.
Why Join Us
- Massive Scale: Your code will run on the BabyBillion app used by millions of kids and parents.
- Build From the Ground Up: Shape the architecture and engineering culture of a flagship consumer app.
- Real Ownership: You build, you ship. No endless approvals.
- Modern Stack: Compose, Coroutines, KMP - we use the best of modern Android.
- Career Growth: Clear path to Senior Android Developer or Tech Lead roles.
- Impact: You are shaping how children and parents experience digital content.
Success in This Role Looks Like
- Features shipped on time with minimal bugs and crashes.
- Smooth, performant app experience across a wide range of Android devices.
- Clean, well-tested code that other engineers enjoy working with.
- Strong collaboration with product, design, and backend teams.
- Steady contribution to the app's architecture and engineering practices.
